Boston Terriers are a Brachycephalic breed (flat faced), there head is square and the muzzle short. This can present health issues related to breathing and temperature regulation. If the nostrils are to narrow the result will be a dog that can't breathe properly. Signs of this are visually narrow nostrils, mouth breathing, and early fatigue when playing. This condition can be remedied by surgically widening the nostrils. This is an indoor breed. They can have difficulty in hot temperatures.
Juvenile Hereditary Cateracts. Are cataracts that occur at a young age and can progress rapidly to blindness. Responsible breeders test their breeding stock. A breeding animal can be tested negative (does not carry the gene) and negative by parentage (both parents of breeding animal were negative). JHC is different from old age cataracts that can occur later in the dogs life just like people. ASK IF YOUR BREEDER CAN PRODUCE RESULTS.
Deafness. Boston terriers can be born deaf. They can be unilaterally deaf of totally deaf. Again, responsible breeders test their stock with a BAER test. This determines whether the dog can hear out of both ears. ASK IF YOUR BREEDER CAN PRODUCE RESULTS.
Luxating Patellas. Both sire and dam should be tested for luxating patellas(kneecaps that slip out) after age one. A one sided luxating patella can be caused by injury but bilateral luxating patellas in the absence of injury are considered inappropriate for breeding. They are rated on a scale of 1-4. If it is a 1 the animal may never have an issue with this defect if kept at a healthy trim weight, 2,3,4 can and do progress to the need for corrective surgery. ASK IF YOUR BREEDER CAN PRODUCE RESULTS.
EYE Diseases. Boston terriers can have eye issues other than cataracts. They can range from mild to serious. Responsible breeders have their breeding animals examined yearly with a CERF exam ( the veterinary Opthamologist will examine the dog) ASK IF YOUR BREEDER CAN PRODUCE RESULTS.
All breeding animals should have an annual exam by the veterinarian just as people do.
These are testing that is recommended by the Boston Terrier Club of America
